HP Aruba Certified Design Expert Written Sample Questions:

1. Refer to exhibit.

A customer has a building that needs a switch upgrade. The customer would like at least 20Gbps for the uplink bandwidth out of each closet. The building wiring plan is shown in Exhibit i. The customer will not consider any cabling upgrades at this point. The current proposal is shown in Exhibit 2.
Which correction must the architect make to the proposal to meet the customer requirements?

A) Add an aggregation layer, and connect wiring closet switches to the aggregation layer on Smart Rate pons.
B) Add a mode conditioning cable for each link between the wiring closet switches and the network core.
C) Add an aggregation layer, and connect wiring closet switches to the aggregation layer with SFP+- SR transceivers
D) Change the SR transceivers tor each link between the wiring closet switches and me network core to LRM transceivers

2. A customer has an existing; Aruba wireless solution to provide wireless access for employees. The solution Includes Aps, mobility controllers (MCs) at the network core, and a Mobility Master (MM} A customer would like to set up a separatelymanaged guest network and have the traffic go directly to the DMZ.
What should the architect suggest as the simplest solution that meets the requirements?

A) Double the number of APs and controllers.
B) Add APs in a dedicated AP group to support only the guest network SSID.
C) Use MulitZone, and put a mobility controller in Itie DMZ.
D) Have a dedicated mobility controller in the DMZ managed by the same MM

3. The architect plans to recommend an upgrade to Aruba CX switches
What is one requirement for the new solution that justifies this recommendation?

A) the requirement to support secure IPsec tunneling at the aggregation layer
B) the requirement to support smart Rate at the access layer
C) the requirement to support larger ARP tables at the aggregation layer
D) the requirement to support tunneled-node at the access layer

4. Refer to the exhibit.

A company needs a new wireless solution for its multi-site network. All branch sites must connect to the main site through secure tunnels over the Internet. The customer requires full redundancy for the Mobility Controllers (MC). Including stateful faiEoverand seamless roaming for the main site.
The architect plans to propose:
- 500 RAPS
- 100 APs at the main campus
- two 7205 MCs
- two 7210 MCS
- one MM appliance
The exhibit snows the existing wired network at the main site, which has a single building with two large floors.
Following the best-practices on design, performance and security, where should the architect plan to connect the MCs?
{Potential locations are numbered in the exhibit.)

A) two 7205 MCs at 2; two 7210 MCs at 1
B) one 7205 MC at 3 and one at 4; two 7210 MCs at 1
C) two 7205 MCS at 1; two 7210 MCS at 2
D) all of the MCs at 2

5. Refer to the exhibit.

A customer requires a core switching solution for a very large multi-building campus with about 30;ooo wireless clients and devices. The network will have a flat topology as shown in the exhibit, and MCs will forward all wireless traffic to the core for routing.
The customer had considered Aruba 5400R Series switches, but the architect recommends Aruba S320 switches Instead.
How should the architect justify this recommendation?

A) The 8320 switches have greater performance and larger ARP tables than the 54Q0R Series, as is necessary for a network this size.
B) The 3320 switches support a higher density of 10GbE fiber ports than the 5400R Series.
C) The 8320 switches are required to eliminate the aggregation layer as the customer desires.
D) The 3320 switches offer more extensive mobility integration features with Aruba MCs and APs than the 54C0R Series switches do.
